Spektrum Dx5e and battery power (a tale of woe).

[williamk]

Hello,

Have (had) an Eflite Apprentice with the Spektrum Dx5e transmitter. Had the original Alkaline double A batteries in it. Had been to the flying field about 9 times with it and was still showing 3 out of 4 LED lights on the charge indicator (75% power?). Was flying with a fully charged lipo battery in the plane when I noticed the plane was not responding well to my inputs, so I tried to bring it down. All the sudden I lost all control and the plane went to full throttle. Result was a full speed nose dive into the ground. Major bummer. After the crash I looked at the charge indicator and I was down to 2 out of 4 lights.

So my questions are. What did I do wrong and how can I prevent this from happening again? Another question would be could something else have caused the signal loss? Should I take it that the charge indicator lights are not that accurate? I am pretty new to the hobby so your advice is appreciated.
